4. Safety

General All safety instructions must be read and complied with, as non-

compliance will result in

- Danger to life and limb of the user,

- Impairments to the machine or other property.

In addition to the operating manual, the accident-prevention regulations

in the country where the appliance is used must be complied with.

Intended use The converter should only be used in technically faultless condition, as

intended, in a safety-conscious and hazard-conscious manner, and in

compliance with the instructions in the operating manual.

Malfunctions that impair safety must be eliminated without delay.

The converter is designed exclusively for the following operations:

- Connection and operation of Weber MT high-frequency internal

vibrators of the types IV, IV-D (EFU 1.3) or IV-S

(only EFU 2.7-Twin)

Non-intended use Unless used as intended, the device involves a risk of personal injury

and property damage. The device is expressly not suitable for:

- Use as a step.

- The connection of other devices.

The responsibility for any damage arising from non-intended use falls

on the owner / operator rather than the manufacturer.

Requirements on the

operator

This converter may only be operated by suitable operators who are 18

years or older. They must be instructed on how to operate the device

by the owner or by the owner's assigned personnel and need to be

physically and mentally t to use the device.

Personal

protective equipment

Personal protective equipment consisting of

- Protective goggles

- Hearing protection

- Work shoes or boots with toe guard

must be worn during operation and the execution of maintenance on the

device.

Spare parts, changes

and conversions

Changes and conversions are prohibited unless made with original

Weber MT spare parts. If the machine is modied with other

accessories without the approval of Weber MT, the manufacturer will not

assume liability for any resulting personal injury or property damage.

All maintenance and repairs must be carried out with original Weber MT

spare parts. Untested spare parts may aect the reliability and safety of

the machine.

Prior to commissioning The device must not be operated unless all safety devices

(mechanical and electrical) are complete and operational.

To prevent overload and other types of damage, the device may

only be connected to the mains supply specied on the rating plate.

The mains supply must be equipped with a grounding conductor.

If the device tips over or slides around, plugs or individual cables

on the inside of the device may detach. There is a risk of short

circuits. The device must therefore be set up in a stable position and

secured against tipping over or sliding around.

Damage to the cable may compromise the insulation of individual

wires. There is a risk of short circuits. The cable must therefore be

protected against mechanical damage.

Do not lay the cable across sharp edges and keep it protected

against heat and oil.

There is a risk of short circuits if moisture enters the interior of the

device. Therefore, do not expose the device to rain and do not

operate the device in a wet or moist environment.

The device must not be operated in an explosive atmosphere.

Check if the control and safety devices are eective to prevent

damage from electric current or equipment that was switched on

inadvertently.

During operation To keep connected equipment from being switched on inadvertently,

the device must not be switched on or o by inserting or removing

the connector plug into and from the power outlet.

As individual wires on the inside of the plug or the device may

detach, the cable must not be used for pulling out the power plug.

Check the cable for mechanical damage (e.g. cuts) regularly during

operation in order to prevent short circuits or electric shocks.

To avoid accidents of any kind, the device must not be used unless

all protective xtures are operational. If detecting defects on the

protective xtures, stop operation immediately, disconnect the

device from the power supply by pulling the plug out of the power

outlet and notify your supervisor.

Maintenance / repair The device does not require any maintenance.

Should repairs become necessary, have them performed by trained

professionals.

In case electronic components are aected, the work may only be

performed by a trained electrician.

To ensure safe operation following any necessary repairs, all

protective xtures must be checked.

This includes a check of whether current can pass through the

grounding conductor.

Transport When loading the device with a crane, use lifting gear with sucient

bearing capacity.

When transporting the device on a vehicle, secure the device

against tipping over, rolling away and sliding around.

Inspection Have converters inspected for operationally safe status in

accordance with the regulations applicable in the country of use at

least every 6 months or more frequently if necessary.

5. Operation

Preparing the machine for

initial use

Remove all packaging material.

Check all components for visible damage. Do not start the device

if detecting visible damage. Contact the responsible dealer.

Check if the shipment of the device and its components is

complete.

Set up the device at its place of use.

Operating positions on the device

1 Main switch

2 Device switch “Start”

3 Power outlet

4 Power plug

Connection to the mains

supply

Before connecting the device to the mains supply, perform a

visual inspection to verify that the device is undamaged.

Make sure the mains voltage corresponds to the voltage and

frequency specied on the rating plate.

WARNING! Danger from an electric shock caused by parts

that have become live due to a fault.

Do not connect the converter to a mains supply that is not

protected by an RCD type B residual current circuit breaker.

Insert the plug into a suitable power outlet.

Connection of

internal vibrators Danger of material damage from overload! The power input of the

connected internal vibrators must not exceed the specied output

current of the converter!

ATTENTION

Connect the device to the corresponding power outlet of the

converter (green).

Commissioning of the

converter

CAUTION

Danger of material damage and slight injury if the connected internal

vibrators are switched on inadvertently.

Before connecting the converter, always make sure that the

connected internal vibrators have been switched o at their own

device switch.

Set the main switch (1) to “I” (ON).

Switch the converter on at the device switch “Start” (2).

The converter is switched on, and the equipment can be

connected.

Shutdown of the

converter

Start by shutting down the connected internal vibrators to keep

the internal vibrators from being switched on inadvertently during

the next operation of the converter.

Switch the converter o at the device switch “Start” (2).

Set the main switch to “0” (OFF).

The converter is switched o. The power plug can be pulled out

of the power outlet.

ATTENTION! Danger of material damage! Never pull on the

cable to remove a plug.

6. Maintenance

The device requires next to no maintenance. No maintenance is

needed except for a daily visual inspection of the device and cable

for exterior damage.

If the visual inspection reveals damage on the device, the damage

must be corrected by trained professionals. If in doubt, contact the

responsible Weber MT partner.
